Missing UI

Recently, during a game I typed into the chat. When I pressed my return key to send chat message, my entire UI disappeared. I have no idea what I did or how to undo it. As a result, I was about as much use as a sponge leg during this game, and I let my side down badly.

Is there an easy way of reloading my UI during a game? I may not be the best player, but I would rather be judged on my incompetence than the fact I can't see my UI during a game

The first time mine disappeared I didn't know which key to press either, problem was it was end of game one-on-one, fortunately I won, but I must have tried every key except V. And yes since then I've had the UI disappear a few times by pressing 'Enter' for chat, I can only think I'm accidentally dabbing another key instead but that would mean two are bound to the UI and V is the only one that shows up.

I remapped my GUI-toggle to "I" (or was it "U"?), so pressing "v" won't help... but I dare say that it's not pressing Enter that causes the GUI to disappear, but failing to do so before starting to type and then having the toggle-key as part of the text written.

Yup I do it all the time. Either I don't press enter or I press it twice. But the first I know is either my minimap or entire UI disappears.
